Here's how the government plans to meet housing units requirements

46 residential sites will be up for sale.

According to a report, forty-six residential sites capable of providing 13,600 units, will be included in the 2013-14 Land Sale Programme. Twenty-eight of them are new sites.

Financial Secretary John Tsang announced the move in his 2013-14 Budget today.

In the coming year, all the major sources of land supply for private housing will together provide land capable of building 25,800 flats.

Financial Secretary John Tsang said in his 2013 Budget speech that the Government has provided the Housing Authority with adequate land to build 79,000 public rental housing flats within five years from 2012-13, and about 17,000 Home Ownership Scheme flats within four years from 2016-17.

"As for the supply of private residential flats in 2013, I estimate that 24,000 first-hand units can be offered for sale this year, including 12,000 uncompleted units, for which we are speeding up the processing of their pre-sale consent applications, 8,000 uncompleted units ready for pre-sale and 4,000 unsold units in completed projects."

Mr Tsang said the land sale programme will include nine sites for commercial or business use and one hotel-only site, providing a total floor area of 330,000 square metres and 300 hotel rooms.

The Government will expedite the development of the Kowloon East core business district, which can provide an office floor area of four million square metres. It is considering expediting the release of two clusters of government sites, which will provide a floor area of 500,000 square metres.

It will also continue to relocate government departments from the Central Business District. It is now proceeding with the relocation of departments in the three government office buildings on the Wan Chai waterfront.

"We shall put up the three government office buildings in Wan Chai for sale in due course, which is expected to provide a floor area of 175,000 square metres."

Mr Tsang said the Government will continue to plan and take forward infrastructure projects to enhance the external connectivity of the transport network, foster economic development and enhance quality of life.

"The estimated capital works expenditure for 2013-14 exceeds $70 billion. By late March, our total commitments for capital projects are expected to be over $310 billion."

The Government is conducting a study to examine the technical feasibility and assess the environmental impact of the proposed construction of Container Terminal 10 on Tsing Yi. It will also seek funding approval for the detailed design of a second tunnel linking Tseung Kwan O and urban Kowloon.

Others measures include using $20 billion for the construction and refurbishment of several public hospitals and clinics, including the construction of Tin Shui Wai Hospital and the Centre of Excellence in Paediatrics, the refurbishment of Hong Kong Buddhist Hospital and the reprovisioning of the Yau Ma Tei Specialist Clinic.
